(Cl. 248-430) This invention relates to a seat seat from fore and aft shocks.

The principal object of this invention is to provide an improved rugged, low cost shock absorbing mechanism for isolating a vehicle seat from fore and aft shocks.

Another object is to simplify the fore and aft shock support for isolating a assembly byincorporating it into the seat adjusting assembly. t

Other objects and advantages will be pointed out in, or be apparent from, the specification and claims, as will obvious modifications 015 the single embodiment shown in the drawings, in which:'

FIG. 1 is a view in front elevation of a vehicle seat embodying the present invention and having portions the release mechanism for the seat adjusting mechanism.

FIG. 5 is a View takenon line 5-5 of FIG. 2 showing the seat adjusting mechanism logked in position.

FIG. 6 is a View similar to FIG, 5 showing the seat adjustment.

Each aligned with a rail 14 secured to the lo'and includes'roller assemblies to support the seat for fore and aft movement. Each roller assembly includes a cylindrical roller 18 rota-tably carried on a pin 20 between the upstanding bracket portions. The ends of the pin project beyond these bracket portions to V rotatably support the generally frusto-conical outer rollers appended claims.

in a number of fore and aft positions by inserting rod 24 in any one of the-holes26 in channel member 28, which is secured to the support 16' as described hereinafter. .The

latchrod' is suspended beneath the seat for longitudinal. rnovement in L-bracket 3t}, plate 32 and inverted channel Referring to a 5 is rotated upward and the rod will move inward'due to y The seat moves fieely on the rpllers and can be locked fwith-the plate.

.and 6 the rodlis released irom handle 36 on the end of the jrod 38.rides outward on cam washer with the rod, it will project through the hole, locking the seat in position. If the seat is not properly aligned, the rod will bear against the inside surface of channel member 28 and on fore or afit movemengthe rod will snap into the first hole, which is moved into alignment with the rod.

The. channel member 28 is pivoted on the end of rod 48 and is provided with a slot 50 through which rod 24 extends. The channel will ride on the rod during fore and aft movement of from being moved too far in either direction so that it falls off of the rollers. The rod 48 is bent in three right angles to extend through hole 52 provided inthe wall of support 10. Rubber bushings 54 and 56 arernounted on the lower end of rod 43 on either sideof the wall and are held in position by washers 58 and nuts 60. Referring to FIG. 2 it can be seen that any fore and aft motion of the seat will cause the rod 48 to pivot at the intersection of the rod and wall of the support 10. On forward motion, the lower portion of bushing 5'4 and the upper portion of bushing 56 will be compressed, and on aft motion, the upper portion of bushing 54 and the lower portion of bushing 56 will be compressed. Any abrupt motion either fore or aft will therefore be quickly absorbed by the bushings. This structure is of simple construction and combines the seat adjusting and shock absorbing assembly into a single unit. Although but a single embodiment of the present invention has been illustrated and described, it will be ap parent to those skilled in the art that variouschanges and modifications may be made therein without departing from the spirit of the invention or from the scope of the We claim: M 1. A vehicle seat support comprising, a stationary mema carriage member mounted on respect to the stationary tween the stationary member and carriage member, a shock absorber including a rod having a transversely extending end and a longitudinally extending end, the transversely extending end being pivotally connected to one of the members, the longitudinally extending end being pivotally connected to the other member through yieldable resilient means.

. 2. Thesea-t support according to claim 1 in which the stationary member includes therein, the. longitudinally passing through the aperture,
